Pain is the most common symptom of sinusitis. You have several different sinuses above and below your eyes as well as behind your nose. Any of these can hurt when you have a sinus infection. Inflammation and swelling cause your sinuses to ache with a dull pressure. You may feel pain in your forehead, on either side of your nose, in your upper jaws and teeth, or between your eyes. This may lead to a headache (see below).
The location of pain and tenderness may depend on which sinus is affected. Other common symptoms of sinusitis include: 1  Headache. 2  Yellow or greenish discharge from the nose or down the back of the throat. 3  Bad breath. 4  Stuffy nose. 5  Cough that produces mucus. 6  Fever. 7  Tooth pain. 8  Reduced sense of taste or smell.
